The Daily Mail reports a recent study by Holiday Autos found that one in 10 couples broke up following a vacation together, with 18 percent of the respondents saying too much time together was an issue with taking trips.

The study, which polled 2,000 adults, found that 40 percent of the couples expected at least one fight each day during the trip and 24 percent said the fighting would begin at the airport with their partner not helping with their luggage. Other issues at the airport included struggling to navigate out of the building and someone wanting control over passports or other documents.

The study also discovered that the most infuriating trip is one that involves driving, followed by trips involving beaches, family trips and bus trips. The most common argument starters were spending too much time together, spending a lot of money, too much alcohol consumption, finding a place to eat or drink and someone pressuring to organize the day’s activities.

“Squabbles about small and insignificant details can often snowball out of proportion,” Corinne Sweet, a relationship expert, told The Daily Mail. “It’s important to learn to stop an argument before it explodes. Take a deep breath and time out to think.”
